You should produce documentation sufficient to get the job done without wasting any effort. How much that is, depends on the size and complexity of the project and the number of developers and stake holders involved. Communications with your customer are critical. You don't want to build something they can't or won't use. Make sure you and your customer know exactly what you are building.
